Because what I assume is heat rash has ruined it for me? I have spent just about every night and part of the day scratching myself like some demented chimp. As a result I’m tired and grumpy. It’s not even that hot, probably about 28 degrees. I look round the pool at other smooth glistening tanned folk and I’m so envious. I’m just not made for heat am I? How do others cope with it.
